Sockets for ICs, Transistors

116-91-432-41-007000, or IC sockets, are devices used to secure integrated circuits (ICs) and transistors onto a circuit board. IC sockets serve to electrically and mechanically connect the ICs to the printed circuit board (PCB) and provide support for the ICs, protecting them from bending, shifting, vibrating and other physical elements that may interfere with normal operation.

Application Fields

IC sockets are used in a variety of different applications across various industries, from military, aerospace, telecommunications, medical, industrial controls and more. These devices also provide a convenience, allowing ICs to be quickly exchanged for repair or upgrade purposes without the risk of damaging the ICs. IC sockets come in various shapes and sizes to suit different types of ICs: pin grid array (PGA), quad flat pack (QFP), quad flat package (QFP) and dual in-line package (DIP).

Working Principle

The working principle of an IC socket is simple: the socket first needs to be soldered onto the printed circuit board (PCB), after which its pins are ready to receive the pins of the ICs. The pins of the socket are then designed to be in contact with the IC pins, either directly or through a series of metal gates. After the IC is placed into the socket, it is held firmly in place and the contact pins are secured. This contact not only provides support for the ICs, it also conducts electricity from the socket to the ICs, allowing the ICs to be operated.

In order to ensure a reliable and secure connection between the ICs and the PCB, IC sockets are made out of materials such as phosphor bronze, beryllium copper or stainless steel. These materials are highly durable and flexible, providing the strength and flexibility required for continuous operation without risk of failure or damage.

Apart from providing reliable electrical connections, IC sockets are also generally waterproof, which prevents the ICs from being damaged by water or other liquids. The sockets also come with various designs that enable them to be used in different installations and applications.
